- With the polarity shown on the thyristor -. A control voltage is applied to the gate terminal Gde's · FET. negative charge carriers from the first zone 2 via the forward-biased pn junction 13 into the second zone 4 and from there via the load path of the FET into the third zone 1. At the same time, holes flow from the p-doped fourth zone 5 via the permeable pn -Transition 16 in the third zone 1 of the thyristor. ', So that the pn junction 14 is in the forward direction; biased That is, the two sub-transistors of the thyristor without the bipolar with conventional thyristors indirectly excited injection is' ■ of holes from the anode-side outer zone immediately: are turned on. This means that the thyristor can be switched on extremely quickly by applying a control voltage to the gate connection G. The control is effected as usual at controlled by field effect 2i> elements, except for dielectric losses r nearly ieistungsios.
Die eingezeichneten Widerstände R 1 und kZ sind zur Funktion des Bauelements, nicht unbedingt erforderlich. Es empfiehlt sich jedoch, wie bei Thyristoren allgemein üblich, zur Verbesserung des du/dt-Verhaltens wenigstens katodenseitig einen Emitter-Basis-Nebenschluß vorzusehen, der durch den Widerstand R 1 repräsentiert wird. Eine weitere Verbesserung kann durch einen anodenseitigen Nebenschluß erreicht werden, der durch den Widerstand R 2 dargestellt ist.The resistances R 1 and kZ shown are not absolutely necessary for the component to function. However, as is generally the case with thyristors, it is recommended to provide an emitter-base shunt at least on the cathode side, which is represented by the resistor R 1 , in order to improve the du / dt behavior. A further improvement can be achieved by a shunt on the anode side, which is represented by the resistor R 2.
Der in F i g. 2 dargestellte Halbleiterkörper weist wie im Prinzipbild nach Fig. 1 eine schwach n-dotierte dritte Zone 1, eine daran angrenzende stark p-dotierte zweite Zone 4_ und eine erste Zone 2 auf, die stark i~> η-dotiert ist. Die vierte Zone 5 ist stark p-dotiert. Die genannten Zonen sind durch die pn-Übergänge 13, 14, 16 voneinander getrennt. Die genannten Zonen bilden den Thyristorteil des Halbleiterkörpers. Weiterhin weist der Halbleiterkörper eine stark η-dotierte Zone 3 auf, «o die auf der Katodenseite an der ersten Oberfläche des Halbleiterkörpers liegt. Diese Zone 3 kann die gleiche Tiefe wie die Zone 2 und die gleiche Dotierungskonzentration wie diese aufweisen. Die Gatezone des Feldeffekttransistors wird durch ein Teil 6 der zweiten ·<> Zone 4_ des Thyristors gebildet. Dieser Teil 6 ist zweckmäßigerweise wenigstens teilweise dünner ausgebildet als der zum Thyristor gehörende Teil der Zone A Die dritte Zone 1 tritt neberi der Gatezone 6 an die Oberfläche des Halbleiterkörpers. Die Zone 3 bildet >° dann die Sourcezone und die Zone 1 die Drainzone des in den Halbleiterkörper integrierten FET.The in F i g. As in the schematic diagram according to FIG. 1, the semiconductor body shown in FIG. 2 has a weakly n-doped third zone 1, an adjoining heavily p-doped second zone 4_ and a first zone 2 which is heavily i ~> η-doped. The fourth zone 5 is heavily p-doped. The mentioned zones are separated from one another by the pn junctions 13, 14, 16. The zones mentioned form the thyristor part of the semiconductor body. Furthermore, the semiconductor body has a heavily η-doped zone 3, which lies on the cathode side on the first surface of the semiconductor body. This zone 3 can have the same depth as zone 2 and the same doping concentration as this. The gate zone of the field effect transistor is formed by part 6 of the second · <> zone 4_ of the thyristor. This part 6 is expediently made at least partially thinner than the part of zone A belonging to the thyristor. The third zone 1 occurs next to the gate zone 6 on the surface of the semiconductor body. Zone 3 then forms the source zone and zone 1 the drain zone of the FET integrated into the semiconductor body.
Zweckmäßigerweise werden zumindest die Zone 3 und die Gatezone 6 durch Ionenimplantation hergestellt. Damit kann man insbesondere eine sehr geringe Dicke der Gatezone 6 und damit eine äußerst kurze Kanallänge des FET erreichen. Damit wird eine hohe Schaltgeschwindigkeit erzielt. Zur Herstellung der Gatezone 6 durch Ionenimplantation empfiehlt es sich, eine aus hochdotiertem, η-leitenden polykristallinem Silicium bestehende Gateelektrode zu verwenden. Die Gateelektrode 17 wird auf einer den Halbleiterkörper bedeckenden Isolierschicht 11 angebracht, die beispielsweise aus Siliciumdioxid S1O2 besteht. Die Gateelektrode 17 weist mindestens eine schräg zum Rand hin abfallende Flanke 18 auf, die als Maske für die Ionenimplantation derart wirkt, daß die Gatezone 6 des FET einen Bereich 7 erhält, der zur Oberfläche des Halbleiterkörpers schräg ansteigende Ranken hat Damit läßt sich die Kanallänge des FET genau einstellen.At least zone 3 and gate zone 6 are expediently produced by ion implantation. This allows, in particular, a very small thickness of the gate zone 6 and thus an extremely short one Reach the channel length of the FET. This achieves a high switching speed. To manufacture the Gate zone 6 by ion implantation, it is advisable to use a highly doped, η-conductive polycrystalline Use silicon existing gate electrode. The gate electrode 17 is on one of the semiconductor bodies covering insulating layer 11 attached, which consists for example of silicon dioxide S1O2. The gate electrode 17 has at least one slope 18 sloping towards the edge, which acts as a mask for the Ion implantation acts in such a way that the gate zone 6 of the FET receives a region 7 which faces the surface of the Semiconductor body has obliquely rising tendrils. This allows the channel length of the FET to be exactly to adjust.
Die erste Zone 2 des Thyristors ist mit einer Katodenelektrode 9 versehen, die an einer von der Zone 3 des FET entfernten Stelle einen Nebenschluß to mit der Zone 4_bildet Die Zone 3 des FET kann mit einem Nebenschluß :19 zur Zone 4_ versehen sein. Für die Funktion des Bauelements ist dieser jedoch nicht unbedingt erforderlich.The first zone 2 of the thyristor is provided with a cathode electrode 9, which is attached to one of the zone 3 of the FET remote location to shunt with the zone 4_bildet Zone 3 of the FET can with a Shunt: 19 to zone 4_ must be provided. For the Function of the component, however, this is not absolutely necessary.
Zur Erläuterung der Funktion des Bauelements wird von der eingezeichneten Polarität der am Thyristor liegenden Spannung ausgegangen. Liegt an_ der Gateelektrode 17 keine Spannung, so ist der pn-Obergang 14 in Sperrichtung vorgespannt und der Thyristor ist gesperrt. Wird an die Gateelektrode 17 positives Potential angelegt, so bildet sich an der Oberfläche des Halbleiterkörpers in der Gatezone 6 des FET ein η-leitender Kanal 8 aus, durch den die Zone 3 mit der dritten Zone 1 verbunden wird. Da'\;t wird der in Sperrichtung vorgespannte pn-übergang 14 überbrückt Es fließen dann negative Ladungsträger von der Katode durch die Zone 4_in die Zone 3 und durch den Kanal 8 in die dritte Zone 1. Damit wird der pn-Übergr« ig 13 in Durchlaßrichtung vorgespannt und die Zone 2 zur Injektion von negativen Ladungsträgern in die Zone 4_veranlaßt. Diese gelangen durch Diffusion zum pn-übergang 14. Gleichzeitig mit dem Fluß von negativen Ladungsträgern durch den Kanal 8 in die Zone 1 wird der pn-übergang 16 in Flußrichtung vorgespannt und zur Injektion von positiven Ladungsträgern in die Zone 1 gebracht. Diese diffundieren zum in Sperrichtung vorgespannten pn-Obergang 14. Der pn-übergang 14 wird dann durch Überschwemmen von Ladungsträgern beider Polarität in Durchlaßrichtung vorgespannt und der Thyristor zündet.To explain the function of the component, the polarity shown on the thyristor is used assumed tension. Is located on the Gate electrode 17 no voltage, the pn junction 14 is biased in the reverse direction and the thyristor is locked. If a positive potential is applied to the gate electrode 17, it is formed on the surface of the Semiconductor body in the gate zone 6 of the FET from an η-conductive channel 8, through which the zone 3 with the third zone 1 is connected. Since '\; t the reverse biased pn junction 14 is bridged Negative charge carriers then flow from the cathode through zone 4_in zone 3 and through the Channel 8 into the third zone 1. The pn-excess 13 is thus biased in the forward direction and Zone 2 initiates the injection of negative charge carriers into Zone 4. These arrive through diffusion to the pn junction 14. Simultaneously with the flow of negative charge carriers through the channel 8 into the In zone 1, the pn junction 16 is biased in the direction of flow and for the injection of positive charge carriers brought into zone 1. These diffuse to the reverse biased pn junction 14. Der pn junction 14 is then caused by flooding of charge carriers of both polarities in the forward direction biased and the thyristor ignites.
Das Ausführungsbeispiel nach F i g. 3 unterscheidet sich von dem nach F i g. 2 lediglich dadurch, da3 h\a die vierte Zone 5 des Thyristors seitlich neben der Katode an der ersten Oberfläche des Halbleiterkörpers angeounet ist. Im übrigen sind dem Ausführungsbeispiel nach F i g. 2 in der Funktion gleiche Teile mi; gleichen Bezugszeichen versehen.The embodiment according to FIG. 3 differs from that according to FIG. 2 only in da3 h \ a the fourth zone 5 of the thyristor is angeounet the side of the cathode at the first surface of the semiconductor body. In addition, the exemplary embodiment according to FIG. 2 functionally identical parts mi; provided with the same reference numerals.
